I have a black togo 30cm birkin which my DH got me from a reseller shop last year. I always have this question - the "black" is not very dark as I would have expected, and there is a very thin shade of greenish colour (a bit metallic) at the end of the handles (the part stiched up with the bag) and at the cover of the keys. The green only appears on the rim / edge of the leather. Is that glue or any finishing material only? Or my bag is not black at all?!
